WALL SAFE on VAULT. ,l

Application filed MarchZG, 1926. Serial Noi`97,56f1.

' The present invention relates to` structures adapted to be built intor houses or otherbuildings to form substantially airtight closets'or vaults, and it has forits object to produce a simple and novel structure in which the exposed wall mayy be made" of vcomparatively heavy material andthe side and rear walls of lightl metal sheets. y f l In order to give rigidity to the vstructure a'sa` whole and preventdistortion, itis necessary to reinforce and stiften the light metal sheets. The object of the present in- ,vent/ion, viewed in one of its aspects, is vto reinforce and stiften the light metal'walls of a' structure of the kind specified, without the use of`any parts other than those required to attach the various wall elements together.

The various features Vof novelty whereby my invention isA characterized willhereinafter vbe pointed out with particularity, in theclaims; but, for a full understanding of `my'invention and [of itsobjects and advantages, reference may be had to the following detailed descriptiontaken in connection with the' accompanying drawings, wherein:

i Figure ljis a front view of a structure embodying my invention, mounted so that the front thereof, which contains the door, lies flush with the face -of the wall of a building; Fig; 2 is a side Vview of the structure; Fig. 8 is a section on an enlarged scale taken on line 3-3 of Figfl; 4 is a perspective view showing the" top4 of the structure with vthe top wall detached;

. shell or casing, having' therein a door open- Y bentrback at right angles to the main portion of the pane] and vform the two front corners of the structure. The two sidewalls 5 and 6 are mad-e of comparatively thin sheet metal, each consisting of a sheet bent Gated. at tand The Side Wang are a'- tached to the flanges or vwings 3 and 4 of the front wall,4 by cuttingl or sawing into the rear vertical edge of'each of these wings or flanges a deep narrow slot 9 into which the forward marginalportionsof the sidewalls tit. A plurality of 'small bolts 10 are vpassed through the anges or wings along lines that will intersect the'grooves into 'which theside wallsfit;v these bolts therefore alsoV passing throughthe l,forward marginal portions of the side walls.,l

Therear wall sections 7 and *Sedo-not vmeet, but each-extends and yfits into a groove 1l in the sideof Aa latreinforcing rib 12 that extends vertically along the kmiddle of the rear wall. Bolts 13, similar to the bolts l0, pass through this reinforcing rib from front to rear, and through, those portions of the rear wall that'lie withingrooves in therib.V f'

It will thus be seen thatthe Afour side walls of the structure are"made of threev sheets or panels and a single reinforcing rib, these four elements being rigidly securedtothese four walls may therefore be fabricated j in the factory, be` shipped in a knocked. down condition, and be bent and assembled l ,atr some remote point.` However, when the structure 1s setup and assembled, 1t 1s eX-' tremely strong and rigid.

The top and bottom of the-structure may `g-,ether by smallbolts.' vThe materialfor benfurther reinforcedt by the top` and bottom walls. In the arrangement shown, thetop Vand bottom walls. consist of simple heavy boards or panels 15.- It willbe seen that the` side and rear` wallsproject" somewhat-above the top of thev front wall andl thewings or flanges on the`latter`; Also,.the upper portion' of the inner( h alf ofthe rear reinforcing rib 12 is cut away so that th-eeffective top of -the'iniier half "ofthis'rib lies in the same horizontal plane-as'the top of the'frontV` wall `as`indicated5ati16- The i top and bottom walls are cutaway on the inner side along'they entire rear edge and along the side edges to within a short distance of the front as indicated atl'?, so as to produce a portion of reduced dimensions that will lit within the side and reary walls when the top and bottom walls are set. in

place; the top and bottom walls resting `inner half of the rear reinforcing rib. That portion of each of the-top and bottom walls that lies in front of the front edges of the side sheets 5 and 6 is left unmutilated so as to conceal the front edges of the upward and downward projections of these sheets. The top and bottom may conveniently be secured in place by means of ordinary wood screws 18 passing through the same into the front wall or panel, and other screws passing through the side and rear walls into the edgesof the top and bottom.

The top and bottom are preferably rset back from the front face of the device so fthat when the device is built `into the wall A of a house or other building, thevjiront edges Vof the top and bottom will be concealed by said wall. Consequently only the front face of front wall of the device is exposedto view when the latter is built in and is, therefore,

-the only outer surface of the device that needsbe attractively finished.

VhileI have illustrated and described ywith particularity only a single preferred vform of my invention, l do Vnot desire to be limited to. the exact structural details thus illustratedand described; but intend to'cover all forms and arrangements which vcome within Vthe definitions of my invention yconstituting the appended claims.

I claim: v l. A shell comprising a thick front wall having rearwardly-directed y wings at the sides, side and rear wallsv of sheet metal, Y

said wings having deep narrow longitudinal grooves in their rear edges, the forward marginal portions of the side walls fitting into said grooves and being adapted to be 4movedV into and out of the grooves through the open sidesof the latter, and fastening means passing through each wing and that portion of the side wall embraced thereby.

2. A shell comprisinga front wall, side walls. Vof sheet metal extended laterally at f theirrear ends to form twov vrear vwall sec tions, a bracing striplying between said rea'r wall'sections and having deep grooves into and formingthe 'front portions of the side Y walls, saidv pieces having deep grooves extending.- lengthwise thereof in their rear edges, sheet metal side wall members fitted` at their front ends into said grooves, said.

thick rearwardly-directed wings at the sides,

each wing having a deep groove Aextending lengthwise .in its rearedge, two sheet metal elements each bent'to form a side wall and a rear wall section, the front ends of each of said sheet metalL elements being fitted into one of the aforesaid grooves, and avbracing strip lying between said rear wall sections and having in opposed sides deep grooves into which the said sections fit. y 'Y v5. A shell comprising a front wall having thick rearwardly-directed wings at the sides, each wing having a deep groove extending lengthwise in its rear edge, two sheet metal elements each bent to form a side walland a rear wall section, the front ends of each of said sheet metal elements being fitted-into one of the aforesaid grooves, a bracing strip lying between said rear wall sections and having in opposed sides deep grooves into which the said sections lit, and bolts passing through said ywings and said bracing strip and through the sheetvmetal portions embraced thereby. i f y 6. A shell' comprising a front wall having thick rearwardly-directed wings at the sides, each wing having` a deep groove extending Alengthwise in its rear edge, two sheet metal elements each bent to form a side wall and a rear wall section, the front ends of eachfof said sheet metal elements being fitted into one of the aforesaid grooves, a bracing strip lying between said rear wall sections and having in opposed sides deep grooves into which the said sections tit, said sheet metal elements projecting vabove said front'V wall and said wings, the inner half of the Vupper end of said strip heilig cut away. to bring the effective top thereof in the plane of the top of the front wall, and a top wall resting on said front wall and its wings and on the effective top of theinner portion of the bracing strip and having portions overlying the upper edges of said sheet metal elements.

ln testimony whereof, I sign this specification. l
